log4j: how to get a Logger
Hi,
The log4j.xml lets one configure a number of loggers, but can someone tell
me the preferred way of how to actually retrieve a Logger object, configured
by that file, in my own servicemix components to use for logging? Is there
any shared LoggerFactory etc. that one should use?
thanks //David

Maven Dependencies on SMX 3.2.2

Hi,
we have a problem building our SU and SA projects with the current 3.2.2
release using maven. There are some dependencies missing since some
days. I'll guess there was a cleanup on apache-snapshots and now some
files are missing.
Is there any way to resolve this?
Here are our build failures:
Missing:
- ----------
1) org.apache.xbean:xbean-classloader:jar:3.3-SNAPSHOT
~ Try downloading the file manually from the project website.
~ Then, install it using the command:
~ mvn install:install-file -DgroupId=org.apache.xbean
- -DartifactId=xbean-classloader -Dversion=3.3-SNAPSHOT -Dpackaging=jar
- -Dfile=/path/to/file
~ Alternatively, if you host your own repository you can deploy the file
there:
~ mvn deploy:deploy-file -DgroupId=org.apache.xbean
- -DartifactId=xbean-classloader -Dversion=3.3-SNAPSHOT -Dpackaging=jar
- -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]
~ Path to dependency:
~ 1) org.apache.servicemix.tooling:jbi-maven-plugin:maven-plugin:3.2.2
~ 2) org.apache.servicemix:servicemix-core:jar:3.2.2
~ 3) org.apache.xbean:xbean-server:jar:3.3
~ 4) org.apache.xbean:xbean-classloader:jar:3.3-SNAPSHOT
2) org.apache.xbean:xbean-kernel:jar:3.3-SNAPSHOT

The Jakarta Commons Logging (JCL) wrapper is only there to mask the
actual implementation and according to the guy who created JCL is a
misuse of JCL. I have a writeup about Java logging available here if
you're interested:

This is an implementation detail of servicemix and has nothing to do
with log4j or JCL

Thanks, now I get it. The motivation for the wrapper I assume has to do with
things like the Log class listening to changes in the log4j.xml at runtime,
and such.

log4j is the implementation and commons logging a wrapper. So by default
log4j is the logger behind the commons logging in servicemix.
Log logger = LogFactory.getLog(YourClass.class);
is one way to obtain the logger.
If you want your logger to log in another file or whatever you should
prepare the conf/log4j.xml which is possible at runtime.

hi and thankt,
yes, I am building my own BC. At any rate I really need more control than to
just use the logger of the component. I want different loggers for different
purposes. I just want to create a logger for a specific class from scratch.
Further I'm confused about that the "logger" member variable of the
component is of a class org.apache.commons.logging.Log, not the log4j class
org.apache.log4j.Logger. What's the difference between these?
Right now I'm trying out things like
LogManager.getLogger(this.getClass());
But I don't quite get it to do what I want.

David,
If you are building your own components, you can extends
DefaultComponent which has a logger preconfigured. Most people aren't
building their own JBI component though, they are using our components
and e.g. adding POJOs to the servicemix-bean component. For those too,
we have convenience base classes (like
org.apache.servicemix.bean.support.BeanSupport) which have the logger
preconfigured.
Regards,
Gert
